The Natural Hazards Review project will develop a framework and best practice approach to characterise natural hazards and seek to improve methodologies where current approaches are inefficient. This is to improve energy system infrastructure design and the project is intended to share knowledge of natural hazards across sectors. The project will be completed in three stages. Phase one will focus on a gap analysis. Phase two will look at developing a series of improved methodologies from the gaps identified in phase one, and phase three will demonstrate how to apply these methodologies. Finally, phase 3 will develop a “how to” guide for use by project engineers.
Hailstones are a solid form of precipitation formed within large convective storms (i.e. thunderstorms). Smaller hailstones do require consideration, principally due to the hazard created when a depth of hail settles on the ground or on the roof of a structure. The depth of hail is also important as, like snow, the weight could cause roofs of buildings to collapse.However, much larger hailstones (diameters greater than 50 mm) are occasionally produced by violent storms. These hailstones can cause considerable damage.
